Definitions

  • the invention relates to an elastic floor covering web made of a pile fabric as the upper fabric web, which has an opening for the passage of water, the pole-holding support, the underside of which is only partially coated with a thermoplastic forming between the openings, and an elastic lower one Material web which also has openings for water to pass through and the top of which is at least partially formed by a thermoplastic which forms thermoplastic regions between the openings and is firmly connected to the upper material web.
  • the invention relates to a method for producing such a floor covering web, in which the two webs are moved synchronously and guided so that they run towards each other before the connection and the underside of the upper web and the top of the lower web are on the same side, and in which the thermoplastic on the underside of the upper web is at least partially plasticized by heating, whereupon the two webs are pressed against one another and joined together.
  • a method of this kind is already known from GB-A-971 958.
  • the invention is concerned with so-called artificial turf for sports fields etc. and with a method for their production.
  • Such artificial turf is already available on the market in which the upper web in use has a base support in which the pile threads or ribbon are anchored and which is completely or partially coated on the back with a thermoplastic material, for example soft PVC is, among other things for the purpose of fixing the pile threads even better in the base carrier.
  • the lower web in use is a closed or perforated elastic mat which consists of a core, for example covered with soft PVC, made of a fabric, a knitted fabric or the like. Both webs are permanently connected.
  • a first part of the invention was to provide a water-permeable and elastic floor covering for sports fields and the like, which can be produced relatively easily and reliably.
  • a second sub-task consisted of specifying a simple method for connecting the two material webs, which had to be carried out before the floor covering was laid, and which can also be carried out continuously in order to use it to cheaply charge larger batches of the two material webs, for example in rolled-up form and to be able to connect with each other permanently.
  • thermoplastic areas of the upper web being welded to thermoplastic areas of the lower web
  • thermoplastic areas of both webs are at least partially plasticized before being pressed against one another by at least one heat source, and that the floor covering web is placed on a conveyor belt for cooling after being pressed against one another (second subtask).
  • the above-mentioned process could also be called hot gluing.
  • the method according to the invention leads to a connection, the character of which can be controlled extremely easily, since it is possible to vary as desired between full-area gluing or welding and only partial welding; For example, one could heat the material webs to be connected to one another only in strip-shaped areas which extend in the longitudinal direction of the material web and are arranged at a transverse distance from one another, with the width and number of strips being freely selectable - all that is required is appropriately trained and arranged heat sources.
  • Infrared radiators are particularly recommended as such, so that a preferred embodiment of the method according to the invention is characterized by the use of at least one infrared radiator as a heat source.
  • thermoplastic material In order to eliminate the risk of burning the thermoplastic material, it is advisable to preheat the underside of the flooring material web and the top of the underlay material web before the two webs are brought together and plasticize them immediately before they are placed against one another in that the heat radiation from at least one infrared radiator in the the gussets formed during merging is set up. In this way, it is not necessary to heat with as high energy densities as if the thermoplastic material of the two webs is heated in one pass from the cold state to softening.
  • the invention Since the application of the method according to the invention makes it possible to avoid the processing of an adhesive and high contact pressures when connecting the two webs of material to one another, the invention finally also opens up a way of producing an artificial lawn which contains a large number of small water reservoirs by means of which an artificial one can be found Sports field with a lawn in hot countries can be "air-conditioned" to a certain extent.
  • underlay material web which consists at least on its surface of a thermoplastic material and has trough-shaped depressions on its upper side
  • a water-permeable flooring product web is also used
  • essentially only the wheels of the trough-shaped Wells are welded to the back coating of the flooring material web and so at least partially maintain the wells. If you sprinkle such an artificial lawn, the water runs through the upper web, but is then partially retained by the trough-shaped depressions, so that the evaporating water keeps the surface of a sports field relatively cool.
  • FIG. 1 shows a piece of a lawn track (upper product web) 10 which can be used as a floor covering and which essentially consists of a textile base support 12 and anchored ribbon 14.
  • the base support 12 can be, for example, a woven or knitted fabric made of plastic yarns, while the pile ribbons 14 are expediently made from thermoplastic materials.
  • the base support 12 is coated on its underside with a so-called back coating compound 16, and only partially in the embodiment shown in order to make the turf track water-permeable.
  • the piece of a backing sheet (lower fabric web) 20 shown in FIG. 2 consists in the preferred embodiment of a woven fabric, a knitted fabric or a knitted fabric made of core threads 22 and a covering mass 24, which forms cushion-like, protruding knobs 26 and leaves openings 28 open, so that the underlay 20 is permeable to water.
  • the backing composition 16 and the coating composition 24 preferably consist at least essentially of thermoplastic materials and in particular both of soft PVC.
  • FIG. 3 shows a second, preferred embodiment of the floor covering web of the invention, the same reference numerals as in FIGS. 1 and 2 being used.
  • the underlay 20 has trough-shaped depressions 100 on its upper side, which are formed according to the invention in that when the coating composition 24 is applied to the textile core of the underlay 20, the material is slightly over at the edges of the knob-shaped cushion areas lets the textile core flow out (downwards during manufacture).
  • the coating composition 24 is applied to the textile core of the underlay 20
  • the material is slightly over at the edges of the knob-shaped cushion areas lets the textile core flow out (downwards during manufacture).
  • only the upwardly projecting edge regions 102 of the depressions 100 are now welded to the turf track, so that the trough-shaped depressions 100 are at least substantially retained and can partially retain water that has seeped through the openings in the turf track.
  • the system according to the invention shown in FIGS. 4 to 6 for carrying out a particularly advantageous embodiment of the method according to the invention has two rotatably mounted support rods 30 and 32 for a turf roller 34 and an underlay roller 36, from which the two webs are drawn off. They initially run over support rollers 38, which are arranged in a horizontal plane, so that the material webs also run horizontally, with the sides to be joined later turned upwards. Then the two webs are guided over two cooling rollers 40 which, like the support rollers 38, are rotatably mounted, but are driven and cooled in opposite directions by means not shown. You are at such a distance from each other that the two webs with the sides to be joined together are placed against each other under slight pressure.
  • infrared radiators 44 are arranged above the turf track 10 and the underlay sheet 20 in front of the cooling rollers, which serve to preheat the back coating material 16 of the turf sheet and the coating composition 24 of the underlay sheet. They consist essentially of a heating element 46 and a housing 50 having a concave mirror 48, all of which extend over the entire width of the respective web 10 or 20 and are designed and arranged such that the focus line 52 of each of the infrared radiators is in the plane the underside of the turf track 10 or the top of the underlay sheet 20 comes to rest.
  • the system is designed so that the speed of the two webs is in the order of 1 to 3 meters per minute and the temperatures below the infrared radiators 44 and slightly above the two webs are approximately 300 ° Celsius.
  • the temperature in the area of the tip of the gusset 54 and just above the point of contact of the two webs is only about 130 to 150 ° Celsius.
  • the temperatures listed above are sufficient to superficially bring the PVC of the back coating material 16 and the coating material 24 into a pasty state, so that when the two webs are placed against one another by the cooling rollers 40, the webs through the PVC are welded together.
  • the cooling rollers prevent the pole ribbons 14 of the turf track 10 and the knobs 26 of the underlay sheet 20 from being deformed inadmissibly during the heating phase of the method according to the invention.
  • the material webs run over a rotatably mounted deflection roller 60, behind which they are placed on a conveyor belt 62 formed by a wire mesh, with the turf web 10 facing upwards.
  • the conveyor belt 62 is also driven by means not shown so that the material webs between the cooling rollers 40 and the conveyor belt remain at least substantially free of longitudinal tensile stresses.
  • the conveyor belt 62 runs over a frame 64 in which support rollers 66 are rotatably mounted.
  • a cutting device 68 is arranged at a sufficient distance from the welding device above the conveyor belt 62 in order to trim the longitudinal edges of the webs that have cooled in the meantime and thus bring the webs to a predetermined width.
  • This cutting device has a bridge 70 spanning the conveyor belt 62, which is fastened to the frame 64 by means not shown, and in the region of the two longitudinal edges of the webs each has a cutting or wedge-shaped run-up shoe 74 which are arranged between the conveyor belt 62 and the webs and lift the longitudinal edge areas of the webs off the conveyor belt 62.
  • the cutting device has on each side a knife disk 76 driven by an electric motor 72 in order to trim the raised longitudinal edge regions of the material webs. These are pressed in front of the knife disks by hold-down rollers 80 against the overrun shoes 74.
  • the two material webs welded together can then be rolled up to form a roll 84 behind the conveyor belt 62.
  • infrared heaters 44 and 56 can also be replaced by microwave heaters, since in principle all heat sources are suitable for melting the back coating material 16 and the coating material 24, provided chemical changes in these materials can be avoided.
  • Band sources SA-TURN 250 and medium-wave module radiators from Heraeus are particularly preferred as heat sources. Instead of heat sources extending across the entire width of the web, shorter radiators can of course also be used, which are arranged one behind the other to heat the Zwikkels 54, while for the preheating of the two webs in the direction of travel one behind the other and laterally offset radiators can be used.
